Intelligent optimization algorithm combined with rough set theory to solve minimum attribute reduction (MAR) is time consuming due to repeated evaluations of the same position. The algorithm also finds in poor solution quality because individuals are not fully explored in space. This study proposed an algorithm based on quick extraction and multi-strategy social spider optimization (QSSOAR). First, a similarity constraint strategy was called to constrain the initial state of the population. In the iterative process, an adaptive opposition-based learning (AOBL) was used to enlarge the search space. To obtain a reduction with fewer attributes, the dynamic redundancy detection (DRD) strategy was applied to remove redundant attributes in the reduction result. Furthermore, the quick extraction strategy was introduced to avoid multiple repeated computations in this paper. By combining an array with key-value pairs, the corresponding value can be obtained by simple comparison. The proposed algorithm and four representative algorithms were compared on nine UCI datasets. The results show that the proposed algorithm performs well in reduction ability, running time, and convergence speed. Meanwhile, the results confirm the superiority of the algorithm in solving MAR.

Affective image operations are attempts to influence behaviour and stimulate action by evoking affects through images. The paper explores their forms and uses in political conflict, from video activism to war propaganda. Drawing together interdisciplinary research, the chapter develops a theoretical framework for analysing the affective and political force of still and moving images, arguing that the affective structure of images has four layers: Political affects and emotions are triggered by the specific interplay of visual forms, worlds, messages, and reflections. On the basis of this framework, several frequent types of affective image operations can be distinguished, illustrated by brief case studies of political web videos.
